Just wondering, anyone feeling difference between the two on road bikes, performance wise?
On my two bikes, both head tubes are straight, but one has aluminum fork tube and another one is carbon. The latter feels a lot more flexy, especially on climbs I feel I need to employ different hands position to put down power into pedals and not the flex (hands closer to the stem kinda help, but not too comfortable).
When I say flexy, I mean I can rock the handlebars up and down probably +/-1cm or more while standing, it always bothered me. Flex appears to originate somewhere at the fork crown and where fork split.
The front flexy bike is Felt AR, older model with the curved downtube (2013 and older).
On straights and cruising speeds the AR excels.
Does the tapered headtube stiffen up the bike and if so, do you see the benefit of stiffer front end?
